Got one here I’m having a tough time with. Dover 3 stop with the alternate fire recall floor being the 2nd floor (intermediate). When on alternate recall it never slows down at the 2nd floor and just runs terminal to terminal. We have found that CS is not getting up there but only on fire recall. CS picks and the car stops on a normal run. It looks like UC, DC, and CC drive CS. I am not getting any of those up. Having a hard time figuring something specific to fire service that is keeping these relays out. Thanks in advance for any info.
